我正在使用
Android YouTube API示例在我的应用中创建无格式的YouTube播放器.我有一个问题,即缓冲/加载进度条即使在加载并开始播放后也会继续显示在我的视频上.我可以在FragmentDemoActivity示例中重现这一点,并进行一些小的修改：
public class FragmentDemoActivity extends AppCompatActivity implements YouTubePlayer.OnInitializedListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragments_demo);
YouTubePlayerFragment youTubePlayerFragment =
(YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
youTubePlayerFragment.initialize(DeveloperKey.DEVELOPER_KEY,this);
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,YouTubePlayer player,boolean wasRestored) {
if (!wasRestored) {
player.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);
player.loadVideo("nCgQDjiotG0",10);
}
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,YouTubeInitializationResult youTubeInitializationResult) {}
}
我已经将FragmentDemoActivity改为继承AppCompatActivity而不是YouTubeFailureRecoveryActivity,因为文档说这很好.我还在onInitializationSuccess中将播放器样式更改为无边框.最后,我已将cueVideo更改为loadVideo,只是为了触发自动播放.
这种情况发生在包括Nexus 5X在内的多种设备上.我正在使用库版本1.2.2. onInitializationFailure中未触发任何错误.
视频在缓冲后开始播放.该播放器是无铬的.然而,缓冲旋转器永远不会消失.这是一个错误,还是我在做一些我不允许做的事情？
解决方法
我也遇到了这个,它看起来真的像个bug.以下是我设法解决它的方法.
在onInitializationSuccess中,在播放器上设置PlaybackEventListener.覆盖onBuffering并执行以下操作：
ViewGroup ytView = (ViewGroup)ytPlayerFragment.getView();
ProgressBar progressBar;
try {
// As of 2016-02-16,the ProgressBar is at position 0 -> 3 -> 2 in the view tree of the Youtube Player Fragment
ViewGroup child1 = (ViewGroup)ytView.getChildAt(0);
ViewGroup child2 = (ViewGroup)child1.getChildAt(3);
progressBar = (ProgressBar)child2.getChildAt(2);
} catch (Throwable t) {
// As its position may change,we fallback to looking for it
progressBar = findProgressBar(ytView);
// TODO I recommend reporting this problem so that you can update the code in the try branch: direct access is more efficient than searching for it
}
int visibility = isBuffering ? View.VISIBLE : View.INVISIBLE;
if (progressBar != null) {
progressBar.setVisibility(visibility);
// Note that you could store the ProgressBar instance somewhere from here,and use that later instead of accessing it again.
}
findProgressBar方法,在YouTube代码更改时用作后备：
private ProgressBar findProgressBar(View view) {
if (view instanceof ProgressBar) {
return (ProgressBar)view;
} else if (view instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup)view;
for (int i = 0; i < viewGroup.getChildCount(); i++) {
ProgressBar res = findProgressBar(viewGroup.getChildAt(i));
if (res != null) return res;
}
}
return null;
}
这个解决方案对我来说非常好,在播放器缓冲时启用ProgressBar,而在播放器缓冲时启用它.
编辑：如果使用此解决方案的任何人发现此错误已修复或ProgressBar的位置已更改,请分享,以便我可以编辑我的答案,谢谢！
